SPECIFICATION forming part of Letters Patent No 270,989, dated January 23, 1883.

' Application filed October 4, 1882. (No model.)

To all whom itmay concern:

Be it known that I, GEORGE R. SOATES, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful Furnace, of which the following is a specification, ret'erencebeing had to the accompanying drawlugs.

and has for its object to provide a simple and etiicient furnace that will efi'ect economy in fuel and possess a large heating-surface. I

In the drawings, Figure l is a front view of the furnace with the front plate and wall removed. Fig. 2 is a transverse section of the furnace. Fig.3 is a longitudinalsection. Fig. 4 is a horizontal section. Fig. 5 is a front view of the furnace, and Fig. 6 is a front view of the smoke drums and pipes.

Referring to the drawings, A designates the brick casing of my improved furnace, which comprises the front wall, B, rear wall, 0, sides I) D, root E, and bottom F. In the side D .is formed a man-hole or opening, G, and under the bottom at the trout extends the transverse cold-air flue H, having auxiliary vertical lines I I opening up into the furnace through its bottom F, one on each side the heater.

J J J are hot-air flues extending out from the top or root E of the furnace at the rear .and being mounted on cross-bars V V. At the top-of the ash-pit and alongside the grate are arranged angular plates W W, which support the side fire-bricks, X X, protecting the convergent sides M M. The incline of these bricks X X and the angle of plates W W 0bviate any possibility of the bricks falling over into the tire. The front and back of the heater are designed to be also protected by fire-brick.

Y Y are vertical smoke-drums arranged in This invention relates to heating-furnaces,

rear of the heater, and connected at the bottom by a cross-pipe, Z, from which extends a smoke-flue, A, passing up and out at the back of easing A. v From each of drums Y Y extends a smoke-flue,-B, into the heater, and O is another flue, extending directly from the heater to the smoke-flue A. Central flue, U, is provided with a damper, D, by closing which all the smoke is caused to pass through flues B"B into the drums Y Y, down and through pipe Z, and from thence up and out at flue A. The object of this deflection of the smoke is that the heat is retained in the top of the drums, while the smoke passes elf, as above described.

E is a U-shaped water-heater arranged above the grate in the fire-compartment of the heater. E by means of a pipe, F, opening into a Water cylinder, G, inside drum Y. From the bottom of cylinder G the pipe F passes forward up and into one end of heater E. The water-is heated in its passage through heater E, and this hot water passes off through a pipe, H, to a hot-water cylinder, I, arranged inside the other cylinder Y. From this cylinder 1 it is conveyed off by the hot-air pipe H to the Wash-house, green-house, or other desired point or place.

J K are evaporating-pans arranged respectively over the fire-compartment and smokefines.

The operation and advantages of my invention will be readily understood. It is simple, convenient, and easily governed.

I claim as new-- 1. In a furnace, the combination, with the water-heater arranged in the fire-compartment, and the smoke-drums having interior watercylinders of the cold-waterpipe extending into Cold water is conveyed to theheater the cylinder in one of said drums and conveying the water from thence into one end of the heater, and the hot-water pipe conveying the heated water from the heater to the cylinder in the other drum and from thence to its destination, as set forth.

2. In a furnace, the combination of the heater having a water-heater arranged in its fire-compartment, the two smoke-drums in rear thereof, having interior water-cylinders, the crosspipe connecting the drums at their bottom, and

having an upwardlyextending smoke-flue, the I In testimony that I claim the foregoing as pipes or smoke-fines extending from the the my own I have hereto affixed my signature in compartment to the drums, the smoke-flue eX- presence of two witnesses. tending direct from the fire-compartment to 5 the upwardly-extending final-exit smoke-flue, l and having a deflecting-damper, the oold-water pipe, and the hot-water pipe, both leading Witnesses: from different ends of the Water-heater to the WILLIAM W001), interiorcylinders of the smoke-drums, and also 0.

[0 from said cylinders, as set forth.
